the grip is poor, but i'm with you on the fact theyre the comfiest ever!!
I had a pair last year which were kind of deminy looking with a white rubber toe and a material boe at the top, really boat-y looking and they were my favourite shoes in all the world... Then i wore them out one night to an indie night and they got wrecked and battered. Went back to primarni to get another pair and they had stopped doing them... So gutted!!!!
However, I bought about 4 pairs this week in new designs to make up for last years loss!
